When launching the beta patched server, I had an error to activate the loadFromRemoteSources switch.
I had to add the bold part of the code in Launcher.exe.config to be able to launch the server again.
Code:
<runtime>
<loadFromRemoteSources enabled="true" />
<gcConcurrent enabled="true" />
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<publisherPolicy apply="yes" />
<probing privatePath="parts/core;parts/bob" />
</assemblyBinding>
</runtime>
